Wioslea

She bought Luke Skywalker's X-34 landspeeder for Spaceport Speeders, a local Mos Eisley company that bought and sold landspeeders and other vehicles. In order to finance the negotiated upfront fee for passage aboard the Millennium Falcon, Obi-Wan Kenobi used a Jedi mind trick to persuade Wioslea into paying 2,000 credits for the speeder, much more than it was worth.

Tzizvvt

Tzizvvt was a male Brizzit who hailed from Jandoon. Claiming to be a professor of xenoarchaeology searching for a treasure known as "The Eye of the Beyonder", he was believed to be a fugitive from the Empire named Ilna. Setting up residence in Tatooine's sewers, Tzizvvt soon became a figure of derision on the planet, dismissed as a "crazy old storyteller." He had in fact collected some treasures, which he kept in his sewer-bound residence, but kept them secret from the proletarians.

Tzizvvt

He first appeared in "Star Wars", as an unnamed alien in the Cantina sequence, portrayed by Stephen Calcutt. On the set of the film, the character was known as "Snail Head," and was supposed to have been given the proper name of "Illna." The character was largely edited out of the film following re-shoots, but still appears fleetingly in the final cut.

Nabrun Leids

The four-armed Nabrun Leids was a male Morseerian smuggler and pilot-for-hire, flying the Scarlet Vertha. The atmosphere of Morseer consisted mainly of methane, so all Morseerians had to wear a protective mask and suit to shield their vulnerable bodies from deadly gases such as oxygen, similar to the Skakoans. He liked to brag that he could take anyone anywhere for the right price.

Yam'rii

The Yam'rii, also known as the Huk, were a sentient species of insects who hailed from the planet Huk. They loved meat and eggs and had no compunctions about eating the eggs of other sentient species. After gaining access to hyperspace technology, the Yam'rii began an aggressive expansionist phase during which they sought out valuable materials for trade on nearby worlds and founded colonies to exploit them.

Yam'rii

The actual prop used in the film was a puppet constructed by the special effects team in London and filmed on set as part of principal photography. The character was referred to as the "Praying Mantis" during production. An uncredited Jack Purvis, the same actor who portrayed the chief Jawa in the film, hid under the alien's skirt and operated it via strings attached to its limbs. Despite being one of the most intricate and complex props created for the scene, the Praying Mantis is difficult to spot in the final film.

Wuher

Wuher was a male human from Tatooine who worked as a bartender in Chalmun's Spaceport Cantina. Wuher lived on Tatooine all of his life. At the time of the film's release, he was only known as "The Bartender". The Mos Eisley Adventure Set first identified the bartender as "Cedo Partu," but the name never stuck, and the character was later renamed as "Wuher."

The Tonnika Sisters

In "Star Wars", two tall girls appear together in the Cantina scene, wearing matching catsuits, and with braided hair piled high on their heads. Played by real-life friends Christine Hewett and Angela Staines, they were known by the simple production nickname "Space Girls".

The Tonnika Sisters

The Tonnika Sisters were identical twins who became infamous con artists under the New Order. Individually, they were Brea and Senni Tonnika, although they often pretended to be just one woman, Bresenni.

The Tonnika Sisters

In "Galaxy Guide 1: A New Hope," these characters were identified as the interplanetary con-artistes Brea and Senni Tonnika, but the article insisted that the sisters were identical twins, both 1.6 meters tall, while the characters seen on screen were visibly different in height and appearance. Hence, Timothy Zahn's short story "Hammertong: The Tale of the 'Tonnika Sisters'" established a retcon that identified the girls in the Mos Eisley Cantina as Shada D'ukal and Karoly D'ulin, disguised as the Tonnika sisters.
